Description

  The present invention relates to a floor panel connection support structure for connecting and supporting corners of two types of floor panels and a cap used in the connection support structure.

  On a floor where many wires are installed indoors, such as in an office, a certain space is provided between the base floor surface and the floor panel laid above the floor surface, and many wires are arranged in the space. A double floor structure is used. As this type of double floor structure, there is a type in which a floor panel is supported on a floor surface on which a floor panel is based via a support device such as a support leg (for example, see Patent Document 1).

  The floor panel used in this case is formed by placing mortar in a plate shape in a plate shape, and in this case, the end surface is substantially vertical by the mold frame (see Patent Document 1). And the floor panel shape | molded by a formwork in this way is comprised as a GRC floor panel by which the reinforcing bar was embed | buried inside when placing mortar, and is provided as an inexpensive floor panel.

  By the way, when constructing a double floor, when laying the floor panel, the floor panel is cut at the end of the floor by on-site processing and the dimensions are adjusted, but in the GRC floor panel, reinforcing bars are embedded inside Therefore, cutting work becomes difficult and workability at the time of laying the floor panel is deteriorated.

  On the other hand, as a floor panel that is relatively easy to cut, there is a floor panel in which both the front surface and the back surface are covered with metal plates without embedding reinforcing bars (see, for example, Patent Document 2).

  Thus, in the floor panel which covered both surfaces with the metal plate, each peripheral part of the top plate which covers the surface, and the bottom plate which covers the back side is projected and joined in the outer peripheral direction, and the joint part becomes a collar part. It is a floor panel with a hook by protruding.

  In addition, when the floor panel is laid, the flange part protrudes in the direction of extending the surface of the floor panel so that the adjacent panels are flat, and the general part of the floor panel and the flange part are flush with each other. It has become. In addition, since this floor panel with a hook covers both surfaces with a metal plate, it tends to be more expensive than the type disclosed in Patent Document 1.

Therefore, when laying a double-floor floor panel, use a floor panel with a hook at the periphery of the floor that requires on-site processing, and use a GRC floor panel at the center of the floor that does not require any processing. It is possible to construct a double floor that is inexpensive and easy to lay.
